l 4.9 Claims.'

This invention relates to machines by which Work-pieces are coated, itbeing particulariy concerned with the application of, the coat-ing inconnection with another operation. 'An' example of work for which thismachine is well adapted is the cementing of the breast-flaps ofshoe-,soles for the purpose of effecting their'temporary Aattachment tothe sole-bodies 'from which they have been divided. Another fornfoftheinvntion, specic to the present case, is made the subject of anapplication for Letters Patent of the United States. led Simultaneouslyherewith and num,- bered 8,00%, the title oi which is Coating-applyingmachine. i Y

It is a common practice4 in connection with womens shoes to split fromthe grain-side oi a sole a thin flap, which may later b e cemented tothe breast o f a heel attached to the shoe, to furnish a covering forysaiglbreas't.A Between the splitting vand breast-covering operations,yarious other manufacturing steps occur involving the sole. For example,in acement-process "shoe, there are the operations of shank-reducing,roughing of the flesh-side, lthe application of cement and then asolvent thereto, and the pressing of the soleupon the shoe-bottom. Whilethis is being done, the rather frail, loose breastflap is obviouslyliable to injury, as by creasing or tearing. It is an object oi ymyinvention to guard against 'diiiiculties of this character, and withthis in view l have provided a machine which may, among its varioususes, be employed totemporarily attach a breast-nap to theopposedsurface of its sole, to be separated therefrom'when it is to becemented to the heel-breast. As above indicated, this aitacnment may beassociated with other operations upon the work, as thespiitting of theflap from the sole-body. This is not, however, an essential part of thepresent invennon, which, more broadly, is directed i1-@the apttachmentofthe workportions to one another;

For the attainment of my object, T combine means acting between opposedsurfaces, as of a sole-body and a flap divided therefrom, to turn theflap away from the body while it is supported to receive the turningaction, and means for applying cement or other coating material to theseparated surfaces, in the present instance to the surface of the flap.Thereafter, the work is'acted upon by means which brings thework-portions together and applies pressure to them. The flap is thusheld against mutilation, adhering to the sole-bo'dy until its separationfor operations upon it is desired. To facilitate this separation, thecoating is applied over less than the entirelaica' (ci. raf-17) of thesurface, leaving a portion which may be grasped by the operator for itsdetachment. The application of the coating may be by such a de-j vice asa nozzle, and this I have shown as mounted upon a carriage arranged toreciprocate along a table upon which the work is supported. With thenozzle, or other applying device, upon the carriage, a receptacle forthe coating material,` a pump for causing the delivery of said material,and a pressure member for 'the work may be mounted. A movement of thenozzle to bring it intoV and out of applying relation, together withmovement of the pressure member and actuation of the pump, arepreferably causedor controlled', either by the reciprocation of thecarriage or by a raising and lowering of the table. The attachingvoperation is most effectively carried out in connection with anotheroperation Vupon' the Work, an eilicient procedure being to combine theattachment with the division or splitting 'of the flap from thesole-body. For this purpose, "a splliting knife is best mounted upon thecarriage, this knife producing its out during relative move ment betweensaid carriage andthe work in one direction and while the work-Supportingtable is in its elevated position. As the knife divides the flap, itturns it back from the sole-body, giving the nozzle or other applyingdevice access to the j ust severed surface to effect its coating. An'abutment upon the carriage, along which the flap is thus turned, holdssaid ap for the action of the nozzle upon it. During relative movementbetween the operating elements and work in another direction, as, forexample, vone'opposite to the direction of movement during the making ofthe cut, the oppos'edsurfaces "of the ilap and sole-body are broughttogether and pres-- sure applied thereto.

In Letters Patent of the United States No. 1,224,918, Furber, May 8,1917, is disclosed a machine to which my invention may advantageously beapplied. The more essential elements of the apparatus of the patent andthe manner in which they co-operate are as follows: Upon a base Ill ismounted an actuating member I2 (Fig. 3) from the opposite sides of whichproject rolls I4. These rolls lie within inclined slots I6 in the sidesof a work-supporting table I8. By a spring 20 (Fig. 2), interposedbetween a portion of a base and a lug depending from table, said tableis l urged normally to the left as viewed in Figs. 1 and 2 of thedrawings, the interaction of the rolls and slots causing it to occupy atthis timeits lowest position. Movable upon ways 22 extendinglongitudinally at opposite sides of the table is a carriage 24, and xedtransversely upon it are a splitting knife 26 and a gage 28 (Fig. 5)which is a mutilated cylinder adjustable about its axis to determine thedepth of cut of the knife. A rotatable operating member 30 is joined bya link 32 to the carriage 24 to reciprocate this over the table, andbears a cam-34, which, by engagement with a roll 36vupon the table I8,moves said table longitudinally suciently to raise and lower the tableI8 on the rolls I4 transversely of the path of reciprocation ofthe-carriage. At the beginning of an operating cycle a sole S to besplit at the heel-portion to furnish a breast-flap s is laid upon thetable, andthe machine started in operation. The cam 34 shifts the tableto the right (Fig. 1) over the rolls I4 to raise it to splittingposition, andthe -link Y32 moves the carriage 24 to the rightto causethe knife26 to divide the breast-flap from the body of the sole. The cuthaving been completed, the cam frees the table, which travels to theleft Vunder the iniiuence of the spring2il.Y This lowers the table torelieve the work Vof the. pressure of the gage, while the link restoresthe carriage to its initial position, the splitting' operation havingbeen thus completed.

To coat one of the divided surfaces with an adhesive and thus prepareforV the attachment of the two Ysurfaces to each other by pressure overthe coated area, there is mounted upon'one of a pair of standards 40,40, rising from opposite sides of the carriage 24, a cement-receptacle42. Fulcrumed upon a bracket 43 depending from a bar 44 joining thestandards is abell-crank-'lever 46, which, at its lower extremity, hassecured to it arnozzle 48. The outlet-portion 50 of this nozzle is shownas curved forwardly toward the gage 28. It acts upon the work againstthe resistance to displacement offered by a curved abutment-plate 52,depending-from a cross piece 53 forming part of the carriage at theforward side of the gage. A spring 5I joining the bell crank 46 andhence the nozzle to oneof the standards 40 exerts its force to draw saidnozzlel normally toward the plate. A exible pipe 54 connects the nozzleto a pump-cylinder 56 mounted at the lower portion of the lcarriage atone side of the base IU. A piston 58 operates in the cylinder, relativemovement between'the two-being produced by contact of collars 60 and 62upon the piston-rod 64 with normallystationary elements upon the base.This action will later be eX- plained. A pipe 66 delivers cement fromVthe receptacle 42 to the pump-cylinder through a spring check-valve 68,as illustrated in Fig. 4, when relative movement of the cylinder andpiston produces suction. Upon relative movement in the oppositedirection, the drawn-in charge is forced -receive the split-01T flap swhile the charge of cement is being drawn from the receptacle 42 intothe pump-cylinder 56. During the rearward or reverse travel, the nozzleis to be moved in against the flap, which has been raised from the bodyof the sole above the knife and into proximity to the plate 52, and thecement is forced by the pump through the'nozzle upon the inner face ofthe flap. Further, the cemented flap is to be pressed downV upon thesole-body to eiect its adhesion thereto. These operations areaccomplished in the following manner:

The upper arm of the lever 46 is united by a link 10 to a lever 12Yfulcrumed at 13 on the carriage 24. This level' carries two rolls, one,14, turning about thepivotal connection of the link, and the other, 16,rotatable on av stud secured to' the lever between its extremities. Asbest shown in Fig. 1, in the initial position of the carriage 24 therol1v16-rests upon the upper edge of a cam-plateg18. Thisplate4 isadjustable along the path of the carriage by slot-and-screw connections19 to vary the time of its effect. The contact with-,the cam-plate soturns the lever 12 clockwise that the link 10 `correspondingly rotatesthe lever 4B, to .hold the nozzle separated from the plate 52 againsttheY force of the spring 5I. As the carriage advances in its forwardcutting travel, vtheroll 'I6 reaches a downward inoline at the end ofthe cam-plate 18. Now, however, since the table I8 has been raised intoitscutting position by the rolls I4 l and slots I6, an edge ofsaid'table contacts with the roll 14 on the lever 12, so vthe inactiverelation of the nozzle is maintained. This continues until thatoperating period illustrated in Fig. 2 is attained and after thesplitting-off of the flap s has been completed. Now the table is loweredand the travel of the carriageis reversed. lAs the tableedge leaves theroll 14, the spring 5I carries the nozzle into engagement with the flap,which is backed by the plate 52. The bodily movement of the nozzle withthe carriage applies a strip of cement along the center of the flap fromnear its Vjuncture to the sole-body to a point somewhat -removed fromthe free end, which end is to be left uncoated. lAt this time the roll16 strikes and rides up the cam-incline 88, causing thelever-and-link-connections to swing the nozzle to its inactiveposition.l The elements finally assume the relation illustrated inFig.1.

. As to the supply of cement from the receptacle 42 to the 4nozzle 50,inspection of Fig. 1 will show that the operating-cycle starts with thepiston 58 in its iinal discharging position. As the carriage 24 travelsto theright, the cylinder 56 and the piston firstmove together, theirrelation to each othernot changing. The piston-rod 54 passes through aperforated stop-lug 82 upon the base. When, at an intermediate point inthe advance of the cylinder and piston, the collar 50 strikes the lug,it is retained thereby and the piston remains at rest whilethe'travel ofthe cylinder continues. This applies suction to the valve 68, opening itand drawing into the cylinder a charge of cement LLL through the pipe66, as appears in Fig. 2. During the taking in of the charge, the valves69 and 'H are held seated. At the completion of splitting travel of thecarriage 24', the collar 62 has just passed a detent 86 pivoted upon thecamplate 'I8v and urged into the path of the collar by a spring 86. Thedetent retains the piston-rod and piston against rearward movement,while the travel of the cylinder continues. This forces the cement outof the cylinder through the now opened valve 69, the valve 68 beingclosed by the pressure. Delivery of the cement to the nap through thenozzle in its activ-e position occurs, the amount being controlled byadjustment of the spring 15 of the valve 'I I, which may be caused todivert a greater or less quantity through the bypass 13. At the time thenozzle is removed from the flap by the engagement of the roll 7S withthe cam-incline 80, said roll strikes the detent, which it overlaps, andlifts it from the collar 62. The piston now being free to travel withthe cylinder, the discharge from the nozzle 59 ceases because there isno longer a force acting to expel the adhesive from the cylinder. Thecollar 92 moves past the detent, which is restored by the spring 86 toits normal position. The quantity of cement taken into the cylinder andthe beginning and end of its expulsion may be altered by adjustment ofthe cam-plate 'I8 and the collars 69 and 62.

A portion of the length of the nap s having been thus coated, it is tobe pressed against the body of the sole S to cause its adhesion. Shownas pivoted to turn about the same axis as the gage 28, and extendingforwardly from the carriage 2t along the table I8, are arms 92 in thefree extremities of which is rlxed a pressure-rod 92. Between the rodand its pivot-point, each arm has mounted to rotate upon it a roll 94arranged for contact with a table-edge, against which it is drawn by aspring 96 uniting the arm to the base. Noting that the rod is fartherremoved from the pivotal axis than the rolls, and that the rod isconsequently movable through a more extended arc, the relation of theperipheries of the rod and rolls is such that with the table raisedduring the cutting stroke of the splitting knife 29, engagement of saidtable with the rolls so positions the rod that it exerts no pressureupon the work. When, however, the table drops for the return travel, therod is lowered into engagement with the wor-x (Fig. 6) and is draggedover it toward the ap s. This forces the coated under surface againstthe opposite sole-surface to effect adhesion.

To briefly outline the operation of the apparatus, and assuming that abreast-flap s is to be split from a sole S, with the elements located asappears in Fig. 1 of the drawings, the operator places the solelongitudinally of the table I8 with the heel-end pointing inwardly andapplies power to rotate the operating member 39. The cam 34 and thecooperating rolls I4 and slots I@ raise the table, and the link 32 movesthe carriage 24 over the sole, so a flap of a thickness determined bythe setting of the gage 28 is split and left attached to the sole at itsbase. As this occurs, the flap is turned up over the inclined upperbevel of the knife between the abutment-plate 52 and the nozzle 50. Saidnozzle is held spaced from the plate by the successive action of thecam-plate 'I8 and the margin of the table upon the rolls 'IS and'I4,`respectively. The rod 92 is held clear of the Work by the rolls 94resting upon the elevator table. A charge of cement is drawn into thecylinder 56 from the receptacle 42 under the control of the collar 60.The nap-cutting having been completed, the table is lowered, and, as itleaves the roll 14, the spring 5I urges the nozzle 59 downwardly againstthe flap near its base, forcing it against the plate 52. As the tablefalls, the rod 92 is drawn down upon the sole by the spring 9%. Duringthe travel of the carriage 24 rearwardly, the knife is carried frombeneath the flap, the piston 58 is retained by the collar 92 and thedetent 84 and delivers cement from the cylinder through the nozzle uponthe inner face of the flap, as appears in Fig. 5. Upon engagement or theroll 'I8 with the detent 84 and the cam-incline 89, the discharge isstopped and the nozzle is withdrawn from the flap. When the rod 92reaches the flap, it forces it against the body of the sole. Thislast-mentioned effect is illustrated in Fig. 6. The carriage is broughtat the close of the operating cycle to the normal position of Fig. 1. Inthe work thus completed a sufficient portion of the ap is so attached tothe sole by the adhesive that its injury during subsequent operationswill be guarded against, but the free end may readily be grasped by theoperator and the remainder of the flap drawn away from the sole whensuch separation is desired.
